[cisco-voip] Excluding extensions from CDR reporting

[Hames, Joel]

We have a new CCM5.1 installation, so I may ask a few basic questions as
we work through our first deployment.  At the moment, we have
implemented RSI's Call Accounting system and have noticed that our
voicemail extension skews all of our reports significantly.  RSI claims
that this is a Cisco configuration issue and that calls to that
extension should not be passed to the call accounting system.  Our
installer claims that there is no way to filter out reporting to certain
extensions.

Does anyone have experience with this? While we can certainly ignore the
reports of calls inbound and outbound to that extension, I'd like to
clean this up as much as possible.  The graphs of call lengths and call
costs would be much more meaningful without extraneous information like
this.

Thank you,
